David Walliams quipped 'I just worry that you are too old,' before adding on a more serious note 'You’re kind of faultless, well done!'

Simon said: 'I’ve got to tell you Molly, I like you, because you’ve got soul. I really do believe that.'

'She’s like a little Mariah Carey,' added Alesha.

Ready to 'crush' the competition: The nine-14 year olds of dance group Nu Sxool certainly made a confident appearance on stage

The youngster received four yeses, sailing into the next round.

The kids definitely dominated the evening, as the Nu Sxool dance troupe, including nine-14, students from Port Talbot, Wales also proved.

Simon asked the group: 'Can you win? Are you prepared to crush the competition?' to which they answered with an enthusiastic yes.

Slick: The group impressed the panel with their exciting, well-choreographed routine

Their acrobatics- filled slick performance left the judges stunned, and David opened the commentary with: 'The challenge for a dance act is to be original and different and come out here and blow the roof off with as much energy as possible and you did it.'

Simon added: 'You’re like the St. Trinian’s of dance and I like that idea and I think that you could play on that a bit more, so you’ve got a little bit more personality in terms of the image but I thought the choreography was smart and it was tight and fun. You were really good.'

Pulled it off in style: Alesha said to Nu Sxool 'you may be little but you mean business. I love the uniforms, the choreography. Good job, well done'

Alesha said: 'The guys are right, you may be little but you mean business. I love the uniforms, the choreography. Good job, well done.'

With three enthusiastic yeses, Nu Sxool were through to the next round.

The next big girl group? David was especially impressed with B Minor, all aged 13-14

London performance artist Geisha Davis, 28, received mixed reviews for her unusual interpretation of Humpty Dumpty.

After her few curt replies to the judges Simon remarked: 'She'd be fun on a date'.

Clearly disturbed by the strange performance, Alesha said: 'I was absolutely petrified, I thought you were going to come out and strangle me. No from me.'
